When people plan for April and May, the same destinations usually appear on repeat, so here is a fresher option: Trenčín in Slovakia. This is not just another “pretty small town,” but a place with a concrete reason to visit in 2026 — Trenčín holds the title of European Capital of Culture, and the city is shaped not only by its attractive old centre, but also by a rich programme of exhibitions, urban routes, and new cultural spaces. Late spring and early summer are especially well suited to a visit: it is already pleasant for long walks, but the streets still avoid that dense summer pressure when beautiful places start to feel like obstacle courses.
